Power generation at home
by the residential fuel cell system ENE-FARM |
“ENE-FARM” is a new energy generation system, which simultaneously produces electricity and hot water at home. We started the worlds’ first sales of this system in 2009.
ENE-FARM produces electric power by hydrogen (H2) recovered from city gas and oxygen (O2) from air through the reverse electrolysis of water. ENE-FARM is clean and quiet because it produces electricity not through burning gases but by chemical reaction. Even small-capacity units have excellent power generation efficiency and produce high overall efficiency by utilizing waste heat, making ENE-FARM an effective way of using energy, suitable for the 21st “century of the environment”. |

ECO-JOZU is an ecologically effective and economically efficient hot water supply system, which reduces CO2 as well as gas bills, by recovering waste heat which used to be discharged into the air and using it to heat water. In principle, all hot water supply units on sale will be changed to the ECOJOZU type by the end of March 2013.
“WithGas” effectively use a combination of energies including natural energy. For example, “W Power Generation” combines a residential cogeneration system with photovoltaic power generation, while “SOLAMO” is a solar water heating system supported by ECO-JOZU. We are creating more environment-friendly houses according to the type of house. |
